Best Diesel Trucks

When something heavy needs to be hauled, nothing beats a diesel-powered pickup Truck. Of all the petroleum-based powerplants fitted to an automobile, the torque potential of a diesel engine is unrivaled. Here it might be useful to explain; while everyone gets so excited about horsepower, torque is the true expression of an engine’s pulling power. Torque sets a vehicle into motion; horsepower keeps it there once torque has done its job. Perusing these listings, you’ll note the best diesel trucks all post highly significant torque numbers, and further, the higher those torque numbers are the higher the posted towing and payload capacities will be. In other words, if you’re looking to do some heavy duty hauling, a diesel pickup is very likely what you need.

Chevrolet Silverado/GMC Sierra 1500

Chevy’s Silverado and the GMC Sierra are virtual twins, so what’s said for one pretty much goes for the other. Body styles include regular cabs with 6.5-foot beds and 8.2-foot beds; extended cabs with 6.5-foot beds; and crew cabs with 5.75-foot beds or 6.5-foot standard beds. To get diesel power, you’ll opt for at least the LTZ package on a double cab Silverado starting at $40,705 (SLT Sierra/$41,435). The 6.2-liter V8 is a $2,495 option. The engine produces 420 horsepower and 460 ft-lbs of torque and is mated to an eight-speed automatic transmission. Max towing capacity ranges from 9,100 to 12,000 pounds. Both rear-drive and four-wheel drive are offered. If you’re also looking to maximize your luxury quotient, go with the $49,905 Sierra Denali.

You’ll get long (eight-foot) beds with the regular cabs, while double and crew cabs get a choice between eight-foot beds and 6.5-foot beds. The $7,195 turbocharged 6.6-liter diesel V8 makes 397 horsepower and 765 ft-lbs of torque.
